Datasheet File OCR Text:

the max338/MAX339 are monolithic, cmos analog multiplexers (muxes). the 8-channel max338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. the dual, 4- channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. both devices can be used as either a mux or a demux. on-resistance is 400 ? max, and the devices conduct current equally well in both directions. these muxes feature extremely low off leakages (less than 20pa at +25?), and extremely low on-channel leakages (less than 50pa at +25?). the new design offers guaranteed low charge injection (1.5pc typ) and electrostatic discharge (esd) protection greater than 2000v, per method 3015.7. these improved muxes are pin-compatible upgrades for the industry-standard dg508a and dg509a. for similar maxim devices with lower leakage and charge injection but higher on-resis- tance, see the max328 and max329. the max338/MAX339 operate from a single +4.5v to +30v supply or from dual supplies of ?.5v to ?0v. all control inputs (whether address or enable) are ttl compatible (+0.8v to +2.4v) over the full specified tem- perature range and over the ?.5v to ?8v supply range. these parts are fabricated with maxim? 44v sili- con-gate process. ________________________applications data-acquisition systems sample-and-hold circuits test equipment heads-up displays military radios communications systems guidance and control systems pbx, pabx ____________________________features on-resistance, <400? max transition time, <500ns on-resistance match, <10? no-off leakage current, <20pa at +25c 1.5pc charge injection single-supply operation (+4.5v to +30v) bipolar-supply operation (4.5v to 20v) plug-in upgrade for industry-standard dg508a/dg509a rail-to-rail signal handling ttl/cmos-logic compatible esd protection >2000v, per method 3015.7 ordering information max338/MAX339 8-channel/dual 4-channel, low-leakage, cmos analog multiplexers ________________________________________________________________ maxim integrated products 1 cmos decode logic a2 a1 a0 en no8 no7 no6 no5 no4 no3 no2 no1 com v+ v- gnd max338 8-channel single-ended multiplexer 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 a1 a2 gnd v+ no1 v- en a0 top view max338 no5 no6 no7 no8 com no4 no3 no2 dip/so/qsop _____________________pin configurations/functional diagrams/truth tables 19-0272; rev 4; 4/12 ordering information continued at end of data sheet. * contact factory for dice specifications. ** ep = exposed pad *** contact factory for availability. + denotes a lead(pb)-free/rohs-compliant package. for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. pin configurations/functional diagrams/truth tables continued at end of data sheet. general description part temp range pin-package max338 cee+ 0? to +70? 16 qsop max338cpe+ 0? to +70? 16 pdip max338cse+ 0? to +70? 16 narrow so max338c/d 0? to +70? dice* max338eee+ -40? to +85? 16 qsop max338ete+ -40? to +85? 16 tqfn-ep** (5mm x 5mm)

__________applications information operation with supply voltages other than 15v using supply voltages less than ?5v will reduce the analog signal range. the max338/MAX339 switches operate with ?.5v to ?0v bipolar supplies or with a +4.5v to +30v single supply. connect v- to gnd when operating with a single supply. both device types can also operate with unbalanced supplies such as +24v and -5v. the typical operating characteristics graphs show typical on-resistance with 20v, 15v, 10v, and 5v supplies. (switching times increase by a factor of two or more for operation at 5v.) overvoltage protection proper power-supply sequencing is recommended for all cmos devices. do not exceed the absolute maxi- mum ratings, because stresses beyond the listed rat- ings may cause permanent damage to the devices. always sequence v+ on first, then v-, followed by the logic inputs no and com. if power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (figure 1). adding diodes reduces the analog signal range to 1v below v+ and 1v above v-, but does not affect the devices?low switch resistance and low leakage charac- teristics. device operation is unchanged, and the differ- ence between v+ and v- should not exceed 44v. max338/MAX339 8-channel/dual 4-channel, low-leakage, cmos analog multiplexers 6 _______________________________________________________________________________________ ______________________________________________________________pin description v g no com v- v+ figure 1. overvoltage protection using external blocking diodes pin max338 MAX339 dip/so/qsop tqfn-ep dip/so/qsop tqfn-ep name function 1, 15, 16, 15, 14, 13 a0, a2, a1 address inputs 1, 16 15, 14 a0, a1 address inputs 2 16 2 16 en enable 3 1 3 1 v- negative-supply voltage input 4? 2? no1?o14 analog inputs?idirectional 4? 2? no1a?o4a analog inputs?idirectional 8 6 com analog output?idirectional 8, 9 6, 7 coma, comb analog outputs?idirectional 9?2 7?0 no8?o5 analog inputs?idirectional 10?3 8?1 no4b?o1b analog inputs?idirectional 13 11 14 12 v+ positive-supply voltage input 14 12 15 13 gnd ground exposed pad exposed pad (tqfn only). connect ep to v+.
